This domain is found at the N terminus in the protein gp35 from Thermus phage P23-45 and similar sequences from tailed bacteriophages. This protein binds the host's DNA-dependent RNA polymerase (RNAP), inhibiting host gene transcription while allowing transcription of phage genes. Structural studies show this core domain of the protein binds to the RNA beta-flap domain. It consists of a central beta sheet and a N-terminal helix [1, 2].	Domain
